rows into columns

Hi there,
I have a query that returns two rows per each license. What I need to do is to combine those two records into one.
the data looks like this:
AddressType ATTN Line1 UNIT CITY STATE POSTALCODE Country
Mailing Address ATTNTO 1234 SW 21 AVE 12 TOWNNAME STATE 12345 US
Site Address ATTNTO 3456 SW 31 AVE TOWNNAME STATE 12345 US

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.
